Cons

Con

No drag'n'drop file upload

Con

Free option limited to 3 mind maps

Con

No good offline mode

You can only work completely offline when using an iOS or Android device. For your browser there's only a clumsy 'offline mode' available. If you didn't hit the switch before you have the need for working offline (for instance: in a meeting, at a customer's location, in a plane, etc.) than your out of luck... no tool for note taking. Especially with all those HTML5-capable browsers and the Chrome App store (including Desktop apps), this limits the usage of this commercial product.

Con

MindMeister has very poor Evernote integration

Evernote is the number one 'store-everything-archive' when it comes to unstructured data or information. MindMeister markets there Evernote integration as a very cool feature. But this integration is very basic and buggy: only the last 50 (?) notes from Evernote's default notebook are shown in the list, and it takes about 30 seconds to one full minute to generate that list. After that it takes about the same amount of time to add a copy of the selected note as an attachment to a topic. MindMeister support is well aware of this poor implementation, but doesn't put any effort in fixing it.

Con

Expensive compared to the competition

A basic monthly subscription ($92 USD) gives you no more than XMind FREE except PDF exporting. XMind paid with PDF export is $79. $20 less for lifetime use of an app with more features as of writing.

Con

Very basic

Con

The interface has only very basic features.

For example, it lacks the possibility to define a long text under the node title showing it in a permanent way. The software is 1000 less powerful than Microsoft Visio. Meanwhile it should just be more specific.
